SHARPENER-TOOL.

Specification of Letters Patent.

Patented July 2, 1907.

Application filed June 6,1906. Serial No. 264,018.

To all whom it may concern;

Be it known that I, ARTHUR MERTON PARKER, a citizen of the UnitedStates, residing at Los Angeles, in the county of Los Angeles and Stateof California, have invented a new and useful Sharpener-Tool, of whichthe following is a specification.

or like blade can be drawn that each side of the blade may come incontact with a sharpening edge of each of the sharpener bars at the sametime; second, to provide a sharpener frame with a'double seat adapted toreceive,

with means for securing, apair of either triangular or rectangularsharpener bars in position forming a V shaped space between said bars;third,=to provide loop crossbars and double alined seats adapted toreceive a pair of sharpener steels with a simple means for securing saidsteels upon said seats, to form all shape space; fourth, to provide ashoulder inclined towardthe sharpener-bars adapted to serve as a guidein sharpening scissors and shears, and a shoulder at the opposite sideof the frame, 'at right angles with the adjacent sharpener bar, adaptedto serve as a guide in sharpening skates; and fifth, to provide in asharpener tool using a bar or steel or steels an abrasive that willsmooth or finish the edgeof the blades sharpened. I attain these objectsby the novel features of construction herein described and illustratedin the accompanying drawing in which Figure 1 is a top plan of myimprovement showing a glass-cutter, glass-breaker andcork-screw-can-opener combination attached to the stock, formingconvenient auxiliary devices; the corkscrew-can-opener combination beinga modification of the combination tool patented to me May 2, 1905 andnumbered 789,103. Fig. 2 is a perspective view of the device showing amodification of the sharpener bar. Fig. 3 is a transverse section on theline 3 3 of Fig.1. Fig. 4 is a section on the line 4 4 of Fig. 2. Fig. 5is a perspective view of the triangular sharpener bars as shown-in Figs.1 and 3. Fig. 6 is a perspective view of the rectangular sharpener barsas shown in Figs. 2 and 4. Fig. 7 is a perspective view of the block ofabrasive material, having a coarse and a fine side, as shown in Figs. 1and 2. Fig. 8 is a plan view of the blank from which the can-openerblade is formed, and Fig. 9 is a side elevation of the blank after it isbent to form the opener blade and showing the rivet as it would appearafter the blade is secured to the frame.

Similar letters refer to similar parts throughout the several views.

The sides or handle a a, the parallel walls b b, the perforating point0, the diverging wall (1 with its scissors and shear sharpener shouldere, wall f with its glass-cutter wheel slot g, glass breaker notches h hand skate sharpener shoulder '5, loop cross bar j with its key seat 70,loop cross bars I l with pair of alined diverging seats m m and brackets11 riconstitute the frame or stock of the device. Transverse loop crossbars Z l are recessed to form two pair of alined diverging seats m m toreceive the sharpener bars 0 0 or O O, and the loop cross bar 9' is.

recessed to form key seat It for key p which secures the sharpener barsin the position as shown in Figs. 1, 2, 3

and 4 and permits of the adjustment of said bars 0 0 or' O O. Theshoulder e is inclined inwardly toward the bars and serves as a guide insharpening scissors and shears. The opposite shoulder i has a surface atright angles with the adjacent sharpener bar and serves as a guide insharpening skates. The block of abrasive material q is preferablysecured to the side of a wall b by means of the brackets n 'nrhoweverthe abrasive may be attached to any part of the tool; and in this formof a sharpener, a cylinderof abrasive material inclosing or encirclingone or both thesides a a may be employed.

The construction shown and described provides loop cross-bars and alineddiverging seats adapted to receive, with a simple means for securing apair of sharpener bars in a position forming a V shape space insuringthe sharpening of a blade from both sides at the same time. It is alsoto be seen that either the triangular or rectangular sharpener bars canbe used in these seats and that each pair of the sharpener bars willform the V shape space and perform their functions equally well. Theshoulders provided furnishes the guides in sharpening scissors, shearsand skates, and, further, the abrasive material furnishes the means forsmoothing or finishing the edge of the blades sharpened.

The glass cutter wheel 1" is pivoted in the slot 9; the can-opener blades comprises a blank of the form shown in Fig. 8 having a rivet hole tand a cutting edge u on the end '0, at the opposite end 11) the notchesx x serve as guides within the walls b b when the body of the blade isbent at right angles with said notched end as shown in Fig. 9. Fig. 9also shows the opener end of the blade bent at right angles with thebody of the blade, and the rivet y inserted as shown in Figs. 1 and 2.The notched end to of the opener blade extends above the walls 6 b andbetween the convolutions of the cork-screw z pivoted in a hole, whichprovides a lock for the can-opener, and convenient auxiliary devices ina sharpener tool.

The utility and operation of the device will be readily understood; oneedge of each of the steels will sharpen the blade drawn between the barsforming the V shape space; the shoulders serving as guides in sharpeningscissors, shears and. skates; and the block of abrasive materialfinishing the sharpening process.

Having thus described my invention what I claim and desire to secure byLetters Patent, is-

In a sharpening device the combination of a frame having traverse loopcross bars provided with alined and oppositely inclined seats and witharms or extensions outwardly diverging from the cr0ss-bars,'a pair ofangu- 10 lar sharpener bars adapted to fit in said seatsand at 7specification in the presence of the two subscribing witnesses.
